This paper develops an approach for valuing Internet Service Providers (ISPs). The viewpoint is taken that once access to the Internet is obtained it can then be characterized by non-rivalrous consumption and non-exhaustibility. However, the quality of access is affected by the capacity of the...

We consider a decentralized, two-echelon supply chain where the upper echelon --the supplier-- bears the inventory risk. To service the retailers, the supplier either keeps inventory reserved for each of her customers or else pools inventory to share among her customers. The common insight...

Every weighted tree corresponds naturally to a cooperative game that we call a tree game; it assigns to each subset of leaves the sum of the weights of the minimal subtree spanned by those leaves. In the context of phylogenetic trees, the leaves are species and this assignment captures the...

In this paper we study hedonic coalition formation games in which players' preferences over coalitions are induced by a semi-value of a monotonic simple game with veto control. We consider partitions of the player set in which the winning coalition contains the union of all minimal winning...

We have studied the incentives of forming coalitions in the Airport Problem. It has shown that in this class of games, if coalitions form freely, the Shapley value does not lead to the formation of grand or coalitions with many players. Just a coalition with a few number of players forms to act...

This paper investigates core stability of cooperative, TU games via a fuzzy extension of the totally balanced cover of a TU game. The stability of the core of the fuzzy extension of a game, the concave extension, is shown to reflect the core stability of the original game and vice versa....

"The common-property literature has often focused on the question of efficiency. Here we consider distributional issues instead. How should the benefits of the commons (say, a fishery) be distributed? We approach the question from the viewpoint of ownership rather than income redistribution. "A...

"Institutional approaches to social dilemmas have so far focused on how to create incentive structures that channel individuals' behavior into socially desirable outcomes assuming that everyone is selfish. However, the presumption of universal selfishness is not only empirically invalid but may...

"In this study, individual level behavior is investigated in the context of computer assisted voluntary contribution mechanism public good (VCM) provision experiments and common pool resource (CPR) appropriation experiments. Previous studies of these environments have concentrated on aggregate...
